r-. More specifically our invention is directed to improvements on thetype of folding bed that is mounted on abase having-a plurality ofrollers thus enabling it to be. moved from the closet in which it ishidden when in folded '1r or upright position to any desired location inthe room where it may be unfolded to hori# zontal position for use.Heretofore folding beds of this type have required heavy counterweightsmounted on l the base to prevent the bed from upsetting when unfoldeddue to the moving of the center' of gravity to a position withoutthebase;

There have been some attempts by inventors to overcome this diiiculty bysupplyingad- 2f ditional or supplemental extension legs which moveoutward into extended position when the'bed is lowered but such attemptshave not met with much'success'.

ur invention is directed to means for causing tlie base of aj bedofthis' type to extend insize as the bed is lowered so that the center ofgravity remains within the base and theA stability of thewhole structureis main# n tained; Also wevprovide'l spring means for controlling theaction of folding and unfolding the bed so that a balance between thetwo operations is effected. n A

An object of our invention is to provide, an extensible telescopic baseforfolding beds.

Another object is to provide a bed frame mounted pivotally on such. atelescopic base with connecting members between the frame andI base'wherebylthe base is extended as the 1o bed .frame is swungto horizontalpositionand telescoped: as the frame is swung to vertical position. l vy Another object is toprovide in a bed of this type spring members whichresist the movement of theframeto horizontal position andthe base tolextended position and tend to return themv to folded position. u sAnother object is tofprovidea folding bed of this type of light weightand counter-'balanced to facilitate operation'. 'Y Other: objects andadvantages will bel apparent from the following Ymore detailed de#scriptlon.

i Referring now more particularly to the drawings', 1 is the base,.2 isthe head end, 3 is the rectangular bed spring frame' having cross bar 3aand 4 isone of a pairy of legs pivotally attached to the foot end of theframe. To the base.- 1 at each corner there; of are pivotally securedswivel rollers 5;

The base L comprises a rectangular member having parallel sides4 6, 7, 8and 9 anda U-sliaped member having two parallel side arms 10; and l1vandl a connecting bar 11a. The sides 6 and 7 areyconstructed: of hollowi rectangular metaly forming sleevesl or slideways adapted tosl-idablyreceive thearms 10 and 11` of the U-shapedmember. The spring frame 8y ispivotally mounted at each side to vertical supporting Istandards 12 atpoints 18. The support-ing standards 12 extend inwardly and upwardly ifromf thel sidesv 61 and 7 respectively andare ree'nforced by brackets14 which are secured toside 8, (see Fig." Mounted on the ends of arms10: and llware sol rollers 15 adapted to fit within the hollow sides 6and 7. Mounted on the upper surface at the inner ends 16 and 17 of thesides 6 and 7 respectively are rollers 18 the lower portions of whichextends down into the hollow sides 6 and 7 and are adapted to bearagainst the upper surfacesof the arms 10 and 11 respectively. In the,cross bar 3a of the spring frame 3 are a plurality of holes 19 in any ofwhich may be fastened one end of the spiral expansion springs 20, theother ends being fastened respectively to the members 14 atapproximately their centers4 Smaller spiral expansion springs 21 arepositioned and secured between' depending eyes 22 and 123 attached tomembers 6 and 10 and 7 and 11 respectively. Pivoted at a point 31, onthe frame 3 above 13 when the bed is vin folded position, is one end ofal connecting rod 24 pivotally secured at its otherend to a bracket'25on the U-shaped frame Yadjacent the point of juncture of memberslO and11a. A similar connecting arm is on the other side of the bed. Pivotallyconnected to a bracket 26 fastenedin the middle of member 8 is a metalrod 27. Similarly connected to a bracket 28clocated on the centralYpo-rtion of a cross bar connecting the folding legs 4 is a sleeve 29adaptedfto receive slidably within it the rod 27.` Adjustably secured torod 27 is a stop member 30. V

Having described in detail the elements of our invention, we will nowdescribe its operation.

When not in use the bed is kept in any desirable recess, closet or thelike in the folded position shown in Fig. 1. To use the bed itis'onlynecessary to move it on its rollers to the desired location,grasp the frame 3 near the foot of the bed and swing it downwardly tohorizontal position. It is apparent that as'the frame 3 is moved fromvertical to horizontal position on its pivots 13 the connecting rods24cause the U-shaped base member comprised of members 10, 11, and 11a toslide outwardly from within the slideways of the sides 6 and 7, thuseffectively increasing the area of the base so that the center ofgravity remains within it and the structure remains stable. The rollers15 and 18 minimize vertical friction between members 10 and 6 and 11 and7 and the rollers 5 allow n movement on the iioor thus insuring ease ofvber within the slideways.

as it is raised. Thus as the sto member 30 is secured in position on rod2 it contacts with the sleeve 29 as the bed is lowered and forces thelegs 4 into supporting position for the bed frame and locks them in thisposition. When the operation is reversed gravity causes the legs toswingl back to closed position.

The tension of expansion spring 2O 'may be varied by hooking the headend of spring 20 into the various holes19 provided inthe cross bar 3a.In thisl way counterbalance Vmay be maintained even though the weight ofspring frame 3 may change. I
